I read that as little as 1% Ethylene Glycol will cause bearing damage, but as much as 8% concentration of propylene glycol will not. If this is true, why would we not use propylene?

I just installed a coolant filter and am getting ready to change the coolant, but still trying to decide the best way to go.

Dump the Ford Gold cxxp do a flush and install a ELC good for 600k not a lot to decide, i went with Delo good for 750k i have other things to do than check coolent

ELC is the coolant recommended and used by International for this engine. .

Coolant Flush for changing to ELC

Drain coolant by removing lower radiator hose. Drain block from plug on drivers side of the block. Remove the thermostat. Replace plug in block and put lower hose back on. Put thermostat housing back on without thermostat. Fill with distilled water. run for 5 minutes then drain as above..Fill and run 5 more minutes drain. Put in 1 gallon of Restore an top with distilled water. Drive it for an 60-90 minutes then drain. Flush 2 times with distilled water or whatever it takes to come clear. Put 2 qts of VC-9 and fill with distilled water. Drive it for about 60-90 minutes. Drain and flush after. Flush 3 more times with distilled water untill it come out clean. Replace thermostat or put in a new one. Put hose back, make sure block plug is tight. Add 3.5 gallons of ELC concentrate and top off with distilled water. Make sure to run engine for 5 minutes between flushes to circulate the water good. Have heater on set to hi while doing this to flush the heater core too.

Don't put a lot of stock in those articles. 1% vs. 8% doesn't make much of a difference. They're based on unrealistic scenarios. The couple I've read state something to the effect of: as little as xx% of EG in your crankcase can cause bearing failure. Well duh! What they fail to mention is all the other stuff that had to go wrong to get coolant in your crankcase.

If you've made up your mind to change out the gold junk go with an ELC that's EC-1 rated. As far as warranty work, I think they would have a hard time denying a claim but could make your life really tough proving otherwise.

Thanks to everyone, I'm not worried about the warranty issues. I have read hear about people finding coolant in their oil, so that is my concern. Just trying to think ahead and possibly avoid that problem if it ever happens. I think ELC is the best bet, but just trying to get all the info and opinions. Hopefully within the next few weeks I'll be done. I wish I could get 5 gallon jugs of distilled water!
